The coolant blew out of my 94 Concorde last week. I was down about a
gallon. Car did not overheat, but the temp gauge was nearing the red
zone. I refilled and drove home with no problem.  Since then I have
not used any.  I left the car running in the driveway for a half hour
with no loss.  I checked with the heater on and off.  

Pressure holds at 8.  Cap is rated at 17.  If I pressurize at 20,
fluid blows out the cap until it hits 8.  BUT I did not see any fluid
by the radiator resevoir when the coolant first blew out. It was
difficult to locate any leak at night. I did spot some towards the
firewall on left center side of engine/trans.  

 I doin;t knowof I have ever replace any orig hoses. 12 years,
125,000 mi.  Maybe it's time to do them all. Any Ideas?  I don't like
self healing problems because they are potentially masking a serious
situation.
